Named after Max Buchholz, who invented it in 1921
The principle of a transformer is based on Faraday's law of electromagnetic induction.
Transformers work on the principle of mutual induction between two coils to transfer electrical energy from one circuit to another.
When an alternating current flows through the primary coil, it creates a changing magnetic field which induces a voltage in the secondary coil.
The ratio of the number of turns in the primary coil to the nu...

A resistor is an electrical component that resists the flow of electrical current. Types of transformers include step-up, step-down, isolation, and autotransformers.
Resistors are used to limit current flow in a circuit
Types of transformers include step-up transformers, which increase voltage, and step-down transformers, which decrease voltage
Isolation transformers are used to isolate a circuit from the power source
Auto...
